SPINNING-RING Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed. August 29, 1906. Serial No. 332,518.

To all whom it may concern:

Be it known that I, lVlICI-IAEL H. MALONEY, of Chelsea, in the county ofSuffolk and State of Massachusetts, a citizen of the United States, haveinvented a new and useful Improvement in Spinning-Rings, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification, inexplaining its nature.

My invention relates to an improvement in spinning rings. Spinning ringshave been made either stationary or rotary and the rotary rings havebeen either driven or free to rotate. In the latter case the ring is provided with a traveler, so called, and the ring itself being free torotate is started and kept in motion by the frictional engagement of thetraveler with it, the endeavor having been to so mount the ring that itwill rotate as nearly as possible in harmony with the speed of thetraveler. With the freely rotating ring, also, not only is the motion ofthe ring rotary, but as the ring to rotate must have a certain amount offreedom from contact with the flanges or guides which restrain itsmovement both vertically and radially, the ring must of necessity yieldslightly both vertically and radially to the pull of the thread upon thetraveler. A thorough trial of such a ring has shown that it is anadvance over both the stationary ring and the driven ring, but it hasalso shown that the attempt to have the ring rotate as nearly aspossible in harmony with the speed of the traveler causes difficultieswhich greatly impair the value of the ring and detract from itscommercial value. Nevertheless rapidity of motion and steady speed havealways been considered by the votaries of the rotary ring as essentialto success in ring spinning in order to secure stronger yarn and toenable the traveler to follow greater speed of spin die than is possiblewith a stationary ring, thereby making possible an increase inproduction. I have found, however, that where the ring is thus free tobe caused to rotate rapidly by the friction of the traveler, it tendswhen started to run away from the traveler owing to momentum, and soprevents that evenness of yarn and softness which is desirable. Moreoverthere is a constant gathering of momentum or acceleration which causesconsiderable breakage of yarn during the course of spinning. Thisbreakage is especially noticeable in stopping or starting the frame.When the frame is stopped the movement of each ring continues and drawsfrom the bobbin a certain amount of slack which is taken up with a jerkwhen the frame is started again, causing the yarn to snap.

I have found that it is a mistake to allow the ring to rotate rapidly orto have such adaptability with respect to its rotation that the ringwill gather momentum; that it is only necessary for the ring to yieldwith a vibratory motion slightly and easily as the varying tension ofthe yarn may require and to have only such rotary movement as willenable the ring to yield to excessive friction of the traveler due tothe strain of the yarn; the ring otherwise remaining quiescent. Myinvention therefore is intended to overcome the faults of a freelyrotating ring and consists in a ring mounted on what may be termed acarrier. The ring is mounted upon the carrier in such manner as to yieldeasily to the varying tensions of the yarn, but has no adaptability torotate independently of the carrier. The carrier on the other hand ismounted so as to freely rotate, freely in the sense that it has freedomof rotation but with an adaptability such that it and the ring carriedby it will rotate not in harmony with the traveler so as to gathermomentum or acceleration, but will rotate or give rotarily uponexcessive friction of the traveler due to strain upon the yarn. Theeffect is that the ring will yield with a vibratory motion to theordinary varying tensions upon the yarn and when a strain comes upon theyarn due to the friction of the traveler or for other reason, then inaddition to its vibratory motion above referred to, the ring, or ratherthe ring and its carrier, will yieldingly rotate and prevent astretching or snapping of the yarn. In such embodiment of my invention 1have found that there is no wildness of movement and that there is anoticeable lack of breakage. There is practically no breakage instarting a frame because when the frame is stopped, the ring having nomomentum and moving only intermittently when there is suflicientfrictional contact with the traveler, becomes as it were stationaryimmediately as the power is shut off.

WVith this construction I have succeeded in obtaining not only astronger but a softer spinning frame, work that heretofore could be doneonly by mule spinning, and I have been enabled to use large rings insubstitution for smaller rings formerly necessary in spinning softeryarn or filling, thereby making it possible to obtain larger bobbins andsave time formerly lost in do Hing. Moreover with the improvedconstruction it is found that it is possible to increase the speed ofthe feed roller, thus feeding out more of the roving to be spun intoyarn. While this means taking out some of the twist, it does notmaterially decrease the strength of the yarn, thus I am enabled toproduce from ten to twelve per cent. more yarn without additional costof power and still maintain the strength of any numbered yarn above thescheduled standard of breakage strength of said numbered yarn.Additional increase of product is possible by reason of the adaptabilityof my device to any speed. of spindle. In fact, the production islimited. in no way by ring or traveler as in the old stationary ringstyle of spinning, and the production is therefore limited only by thecapacity of the spindle and frame.

Referring to the drawings :Figure 1 shows a plan of a constructionembodying my invention looking down upon the same. Fig. 2 shows a planof the same construction looking towards the under side of the same.Fig. 3 is a cross section 011 the line 33 of Fig. 1. Fig. 4 is a crosssection on the line 44 of Fig. 1. Fig. 5 is a cross section. on the line55 of Fig. 1.

In the drawings :A is a ring of the ordinary kind having a lower flangea and an upper flange a on which runs the traveler o The ring is looselymounted on what may be termed a carrier B resting on bearings orsupports consisting of projections I) extend ing inwardly from the bodyof the. carrier, the ring being loosely mounted in the sense that it hasa limited degree of vibratory movement and this preferably in both alateral and vertical direction with respect to the carrier but with norotary movement or appreciable rotary movement with respect to thecarrier or at least no such movement with respect to the carrier thatthe ring will gather momentum with respect thereto. It is evident thatthe ring might be mounted to rotate through less than a complete cycleof movement with respect to the carrier and my invention still bepracticed, though in my opinion less effectively. For the purpose ofthus mounting'and retaining the ring there extends upwardly from thecarrier flanges or clips I)? which loosely embrace the lower flange ofthe ring, or in other words, loosely enough to permit of the ring havinga limited degree of vibratory movement and which vibratory movement, assaid before, is preferably both lateral and vertical. As a means forpreventing rotation of the ring with re- 'the base into the support.

spect to the carrier, whichmeans will not interfere with its freevibratory movement, as before described, the ring on the under sidethereof is provided with a dependent lug a which fits into a recess orslot 6 formed in one of the bearings I) (see Fig. 4), on which the ringis resting.

The carrier B is preferably annular in shape or of such shape as willpermit of its having a complete rotary movement. It is supported by abase C. To this base are at-. tached slotted supports a in the slots 0of which the edges of the carrier are contained with the carrier restingupon the supports. The slots 0 in the support 0 are so made that thecarrier will -lit loosely within them so that the carrier will becapable of free rotation. Consequently by reason of this very freedom ofrotation it will have a limited degree of vibratory or vertical andlateral movement.

The carrier B is placed in position with its I edges contained withinthe slots 0 of the support 0 when the device is assembled, by mak ingone of the supports 0 attachable to the base after the carrier has beenplaced in proper position to rest upon and be retained y the othersupports. Such attachment of the support may be made by fastening it tothe base by means of a screw or other detachable fastening c whichfastens through With such a con struction the ring loosely mounted as itis, will yield with a vibratory movement to any slight pull upon theyarn. Such movement is suiiicient to overcome ordinary strains. In caseof more severe strains, however, then the ring will freely rotate, orthe ring and carrier together, until such strain is relieved.Practically the carrier acts as a drag upon the ring enabling it tovibrate but preventing its rotation upon a light strain and providing ameans of rotation to overcome heavier ones.

It is to be understood, of course, that various forms of constructionmay be employed and still embody the spirit of my invention; any form orstyle of base or setting may be used; even the frame itself may be usedfor ithe rest or support for the carrier.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1.
